Title: Hadamard transform coding/decoding method and apparatus for image signals
Inventor: MOCHIZUKI TAKASHI
IPC: H04N19/91
Filed: 1996-01-26
Granted: 2000-04-11
Abstract: In a Hadamard transform coding/decoding method and apparatus, transform coefficients which are obtained through an Hadamard transform operation in an Hadamard transformer 3 are subjected to a bit extract (delete) operation in a bit delete unit 4 to extract 1 bit from the least significant bits of the transform coefficients, 4 bits from the second least significant bits and 7 bits from the third least significant bits and then the extracted bits are output as supplement information Ysup.      In addition, the transform coefficients whose first, second and third least significant bits are deleted, are output from the bit delete unit 4. A bit restoring unit 7 supplements the first, second and third least significant bits of all the transform coefficients on the basis of the 1-bit information, 4-bit information and 7-bit information per block of the supplement information Ysup, which represent the first, second and third least significant bits of the transform coefficients, thereby restoring the transform coefficients. The restored transform coefficients are output to an Hadamard inverse transformer 8 to obtain an image signal.

Abstract: The multilevel convertor includes capacitors (C1,C2...,Cn) for each of its cells. The capacitors have nominally charge voltages proportional to their row in the convertor. The convertor also includes control devices (BT, DA1...,DAn, pe2...,pen) designed to evaluate the voltage source (VECn) of the convertor. As soon as the voltage source (VECn) of the convertor is less than a set value, to suspend the nominal function of the convertor (sd) and to operate switches (T1,T`1,T2,T`2...,Tn,T`n) so that when the voltage (VE) of the voltage source (SE) has a value between zero and a least high nominal charge voltage, it charges all the capacitors of the convertor. When the voltage of the voltage source exceeds the least high nominal charge voltage, the capacitor (C1), nominally charged by this last voltage, is switched out of circuit. The voltage of the voltage source continues to charge the capacitors (C2...,Cn) demanding higher nominal charge voltages until the voltage exceeds that next least high voltage (C2), capacitor (C2) is then switched out, this continues until all the capacitors are charged to their nominal charge voltages. At the end of the complete charging sequence the control device restores the nominal operation of the convertor.

Abstract: The present invention relates to a combination of A and B adhesives (16 and 12 respectively) reacting together through a scrim material (14) in a laminated combination, and wherein the B adhesive (12) has great adherence characteristics to a vinyl nitrile foam (10), and the A adhesive (16) has great adherence characteristics to itself. Thus, a laminate of the A adhesive (16) / scrim (14) / B adhesive (12) to each side of a slit in a vinyl nitrile foam tubular insulation (10), with appropriate release liners (18) covering the outside A adhesive (16), has been found particularly effective. When the release liners (18) are removed and the A adhesives (16) are pressed together, a very strong bond is created closing the slit in the vinyl nitrile foam insulation (10) holding the tubular vinyl nitrile foam (10) in place on the tubular member t o be insulated. Normally, this is utilized in an air conditioning application with the piping or tubes running from the compressor to the air conditioning unit, and wherein vinyl nitrile foam insulation has proven to be the best insulation material for this application.

Abstract: A wheelchair provides a seat mounted to a base preferably through use of a universal joint to provide for selective orientation of the seat. A pair of actuators are interposed between the seat and base so that selective extension and retraction of the actuators orients the seat as desired. A level sensing device(s) provides suitable output signals to control the extension and retraction of the actuators, and thus the final orientation of the seat. This allows a wheelchair occupant to remain level while the chair traverses uneven ground or to selectively reposition the seat to relieve pressure points without the assistance of an attendant.

Abstract: La présente invention concerne un procédé permettant de vérifier si la valeur courante d'un signal de sortie représenant une variable de processus se trouve à l'intérieur de limites acceptables. Ce procédé consiste à établir des données de référence en échantillonnant le signal de sortie représentant une variable de processus de l'installation lorsque l'installation fonctionne en régime permanent et à analyser le signal de sortie échantillonné pour en déduire des données de référence normalisées parmi lesquelles une caractéristique énergie de chaque composante d'une pluralité de composantes de fréquence du signal de sortie échantillonné. La procédure permet de constituer une base de données opérationnelles courantes en échantillonnant un signal représentant une variable de processus lorsque l'installation fonctionne. Le signal de sortie courant échantillonné est analysé pour déduire des données courantes parmi lesquelles une caractéristique normalisée d'énergie de chaque composante d'une pluralité de ses composantes de fréquence. La procédure compare les caractéristiques normalisées d'énergie de chaque composante commune de fréquence des données de référence et des données courantes, et elle déclenche un signal d'instabilité si cette comparaison montre que les caractéristiques d'énergie comparées dépassent une valeur prédéterminée.

Abstract: A method of operating a laser and a gas analyzer to reduce low frequency and high frequency power non-linearity errors passes a laser beam through a sample gas to a detector. Intensity measurements are taken and compared to a reference set of measurements. The reference set of measurements can be calculated by measuring pressure and temperature of the sample gas. The laser wavenumber tuning width is locked to tune a high frequency of an absorption path fringe to a predetermined reference value. The analyzer can be operated without taking a reference set of measurements and the analyzer is much smaller than previous analyzers.
